by 윤종철 29 Apr '05

29 Apr '05

Dear. I installed freesurfer-2004-2-18 version, recently. I have trouble in installing MNI packages as install guideline. [root@kphe pubsw]# ls bin packages ln -s usr/lib/perl5 perl and then, unpacked mni packages under mni directory When I start mritotal, permission error was occured. [root@kphe freesurfer]# mritotal /usr/pubsw/packages/mni/current/bin/mritotal: Permission denied. But, all files in usr directory was already changed to root permission. -rwxrwxrwx 1 root root 87070 Aug 10 2001 mritotal Except perl script, binary files like xfmri was working. I use Redhat Linux 9.0. I don't know what is the problem. Could you help me?

Re: [Freesurfer] Dicom

Thanks Doug, Is there a way of transforming all the *.dcm files into one-volume {img,hdr,mat} file? Nam. >>> Doug Greve <greve(a)nmr.mgh.harvard.edu> 04/28/05 2:56 PM >>> Try mri_convert file.dcm f -ot spm where file.dcm is a dicom file in the series you want to convert (there is no special naming requirements -- in fact the file names can be random). The output will be f001.{img,hdr,mat} f002.{img,hdr,mat} doug Joongnam Yang wrote: > > Hi all, > > I am sorry, since I might have missed the answer. > My question is, the following question by Mr. Ajay Pillai has been answered? > If yes, would someone forward me the answer please? > > Thanks. > Nam. > > >>> Ajay Pillai <pillai(a)ccs.fau.edu> 04/27/05 2:26 PM >>> > Hi, > I am trying to convert my dicom funcional scan images into SPM analyze > (or even AFNI BRIK) format. > > I have about 320 functional volumes of 30 slices each.

Dicom

Hi, I am trying to convert my dicom funcional scan images into SPM analyze (or even AFNI BRIK) format. I have about 320 functional volumes of 30 slices each. So basically I have 9600 .dcm files which I have renamed sequentially for each subject.The first 30 constitute one volume the next 30 next volume and so on. Can mri_convert do this? If so could some one please tell me how? Thank you Ajay

problems generating the filled volume
by wilms 26 Apr '05

26 Apr '05

Dear freesurfers, when I check my mri_converted data after running (1) using <csurf> I find my data shifted relative to the voxel space center (volume index at [128 128 128]) as can be seen in the attached screenshots. The subsequent generation of the "filled" images leaves the cerebellum always attached. I tried to manually set the cutting planes as described in the FreeSurfer Manual (pp. 32-36) but the whole cerebellum is still connected to the brain and always attributed to the left hemisphere. In addition to that I think the bert "orig" data set is smoothed, right? In comparison to bert does my data look much more grainy. Do I have to smooth my data first? Any suggestions in how I can proceed in trying to successfully set the cutting planes are most welcome!

Binary locations--new linux distro
by Brian Schweinsburg, Ph.D. 25 Apr '05

25 Apr '05

Hi, After installing the freesurfer-Linux-rh9-20050415.tar.gz and setting up the SetUpFreeSurfer and FreesurferEnv, I get an error message when csurf loads. It states that it cannot find numerous binaries in /usr/local/freesurfer/beta/bin. This issue seemed to resolve by symbollically linking the my $FREESURFER_HOME/bin directory to previously mentioned one. Is there a place to change where csurf expects to find the binaries? Did I miss it in the FreesurferEnv setup? Thanks for your time, Brian

Hi ! I have the same problem with tksurfer as they detail in the mail (see link). http://www.mail-archive.com/freesurfer@mail.nmr.mgh.harvard.edu/msg00642.ht… I installed last version of freesurfer (20040218) wich doesn't have tksurfer.static. Perhaps it's in an earlier version... Can somebody send it to me ? Thanks

"consider relinking" warnings
by wilms 21 Apr '05

21 Apr '05

Please help a freesurfer beginner: I am just trying to get the FreeSurfer software running on my local (and later on the cluster) machine (debian sarge, P4). When running > recon-all -stage1 -s bert on the bert example data, the script runs smoothly except for lots of "consider relinking" warnings (see below). I sense this might be related to compiler version issues? My question: Are these errors harmful?- If yes, what can I do? - Build the minc-tools on my machine?

RE: [Freesurfer] Problem converting IMA files
by Kristine Beate Walhovd 20 Apr '05

20 Apr '05

Hi Someone told me that using mri_convert -it siemens_dicom <first IMA file> <destination directory> had worked, and I tried that. The files were then converted, but even though I don't get any error messages, there is serious conversion error. In the coronal view, I see black stripes and a quarter of the head is cut off and placed at the other side of the image. When I go through the slices sagitally, I see that it jumps from slice 13 to 56, and there also appears to be some slices of very different (darker) intensities in between. The scans looked excellent when I looked at them at the hospital work station, so this must be a conversion, not quality problem. These are GRAPPA series, could that have anything to do with the problems? Thanks, Kristine -----Original Message----- From: Doug Greve [mailto:greve@nmr.mgh.harvard.edu] Sent: Tue 4/19/2005 2:42 AM To: Kristine Beate Walhovd Cc: freesurfer(a)nmr.mgh.harvard.edu Subject: Re: [Freesurfer] Problem converting IMA files What was your exact command-line?
